Sure-Seal Standard-K® Connectors

RUGGED CONNECTORS FOR A RANGE OF APPLICATIONS

Sure-Seal Standard-K® connectors are rugged, reliable, lightweight and easy to use. Standard-K® connectors are chemical and corrosion-resistant with excellent electrical insulation and stability, making them ideal for applications as diverse as oil field equipment, shipboard circuit breakers, concert audio snakes, mass transit applications, and MRI machines. This series is available in common layouts from 2 pin connectors all the way up to 110 pins. The Standard-K® is manufactured by Sure-Seal Connections, a division of PEI-Genesis. For full details on PEI-Genesis Standard-K® connectors, see the product specifications below.

Quick Connect & Disconnect
Special Acme Threads lock the connector halves together and allow rapid mating and un-mating of the connector halves.

Variety of Shell Styles
Straight or right angle cable-mounted plugs mate with two flange sizes of panel-mounted receptacles. All configurations are available with male or female contacts. Rotational polarization is a standard option to avoid mis-mating connector pairs when more than one connector with the same layout is used on the same system.

Simple Assembly and Termination
Standard-K® has no complicated parts, special tooling, or demanding wire preparation requirements. Assembly of the connector is simple and fool-proof using a soldering iron and a screw driver.

Wide Range of Wire Gauges and Current Carrying Capabilities
Wire sizes from 26 through 4 AWG can be accommodated. Contacts are rated from 5 amps for a size #20 contact up to 80 amps for a size #4 contact.

Choose the contact arrangement from the layouts pictured on pages SK 6 and SK7 or the chart below. Layout designations include a letter prefix indicating the shell size. The coupling diameter of the shells are as follows:

WK = 7/8"
GK = 1-3/16"
SK = 1-5/16"
NK = 1-9/16"
LK = 2-1/2"
